Efficiency:

As any experienced Heathstone player would tell you, the Acidic Swamp Ooze is one of the best neutral basic minion cards avaliable in the game.

For two mana he has huge mana efficiency potential, he is a sturdy two mana minion at 2/3 and on top of that he has the ability to reap huge additional efficiency by destroying whatever Weapon the opponent has equipped during your turn.

Uses and Tactics:

If you are playing against a Warrior, Rogue, Shaman or Hunter however, it is recommended, if possible, to hold onto him until your opponent equips a weapon and then drop him in order to acquire maximum value from this card.
